Sync Anima2D Animations with Player Movement

Hi there, looking for help syncing my saved Animations from Anima2d with my player controller. Here is my 3D Player Movement script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerController : MonoBehaviour {
     
         public float speed = 6.0F;
         public float jumpSpeed = 8.0F;
         public float gravity = 20.0F;
 
         private Vector3 moveDirection = Vector3.zero;
         void Update() {
             CharacterController controller = GetComponent<CharacterController>();
             if (controller.isGrounded) {
                 moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
                 moveDirection = transform.TransformDirection(moveDirection);
                 moveDirection *= speed;
 
                 if (Input.GetButton("Jump"))
                     moveDirection.y = jumpSpeed;
 
             }
             moveDirection.y -= gravity * Time.deltaTime;
             controller.Move(moveDirection * Time.deltaTime);
         }
     }

Essentially, I would like it so the animation sequence for,"Walk Right" plays when the player moves right.

Currently, only Idle Animation plays when the character does anything in the 3d space. I am attempting to add animations that activate on jump, on left movement, on right movement, etc. without much success.

I am an artist that has only recently started learning this, so please help me understand a method to do this, or refer me to an online tutorial that may be of some help. In the past I have asked for help and was met with,"Here's the Scripting Unity Guide link" which is extremely unhelpful.

Thank you!
